⚠️ Safety & Precautions

• ⚠️ Turn the lights OFF and remove the key before starting.
• ⚠️ Let bulbs cool—halogen bulbs can be hot right after use.
• ⚠️ Wear gloves; oils from fingers can shorten bulb life.
• ⚠️ Support the lamp when loosening nuts so it doesn’t drop or scratch paint.

📋 Before You Begin

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the taillight fasteners (inside cargo area)

• Open the liftgate and locate the small interior access cover behind each taillight area.
• Use a plastic trim removal tool to gently pry off the access cover.
• Use a flashlight to clearly see the nuts and wiring.

Step 2: Remove the taillight assembly (one side at a time)

• Use a 10mm socket, 1/4" ratchet, and 6" socket extension to remove the taillight retaining nuts.
• Place the nuts somewhere safe so they don’t fall into the trim.
• From outside, hold the taillight and pull it straight rearward to release the alignment pins (do not pry against paint).
• Tip: Wiggle straight back, not sideways.

Step 3: Remove the bulb socket

• With the lamp loose, locate the tail/brake bulb socket (usually the larger dual-filament socket).
• Twist the socket counterclockwise by hand and pull it out.

Step 4: Replace the bulb

• Put on nitrile gloves.
• Pull the old bulb straight out of the socket.
• Push the new bulb straight into the socket until fully seated.
• Tip: Don’t touch the glass with bare fingers.

Step 5: Reinstall the socket and taillight

• Insert the socket back into the housing and twist clockwise by hand until it locks.
• Align the taillight pins with the body holes, then press straight forward until it seats flush.
• Reinstall the retaining nuts using a 10mm socket, 1/4" ratchet, and 6" socket extension.
• Torque to 7 Nm (62 in-lbs)
• Snap the interior access cover back in place.

Step 6: Repeat on the other side

• Repeat Steps 1–5 for the other taillight.

✅ After Repair
